Qualifier 1 of the Qualifying Round of the 2017 World Baseball Classic was held at Blacktown Baseball Stadium, Sydney, Australia from February 11 to 14, 2016.
Qualifier 1 was a modified double-elimination tournament. The winners of Games 1 and 2 matched up in Game 4, while the losers faced each other in Game 3, an elimination game. The winner of the elimination game (Game 3) then played the loser of the non-elimination game (Game 4), in Game 5, another elimination game. The remaining two teams then played each other in Game 6, to determine the winners of the Qualifier 1.
